Keeley Hawes and her husband, Matthew Macfadyen of Succession, will next appear in an ITV series together.
In a three-part drama Stonehouse, the real-life couple will play opposite each other, retelling the bizarre tale of the disgraced Labour minister (Macfadyen), John Stonehouse, who faked his own death in 1974, leaving his wife (Hawes) and children behind.
Hawes and Macfadyen's performances, as a result of having been married for 18 years, are more authentic, with the Bodyguard star saying it was "a pleasure" to work with her husband again.
"We just had a great time. There's this impression that 'they're married, how's this going to be?' Hawes told The Guardian.
"It was a joy," said the author.
Between 2002 and 2004, the pair co-starred in the spy drama Spooks, and in the black comedy Death at a Funeral in 2007.
Stonehouse follows the titular politician, a rising star in the Labour Party who was later revealed to be a Czech Secret Service spy on a beach in Miami in November 1974. In fact, he was going to begin a new life in Australia with his secretary and mistress Sheila Buckley.
Stonehouse used a different alias after faked his own death, but his scheme lasted only a month before he was apprehended by Australian authorities, despite believing he was a different fugitive.
"What happened to John Stonehouse is a legend," Macfadyen said in February.
"I've always been interested in what motivated him to fake his own death, and leave behind the family he loved and cherished, and a promising political career."
Stonehouse is expected to air on ITV later in the year.
